The effect of the ground granulated blast-furnace slag (GGBFS) addition, the modulus n (mole ratio of SiO2 to Na2 O ) and the concentration of sodium silicate solution on the compressive strength of the ma terial, i e alkali-activated carbonatite cementitious material (AACCMfor short ) was investigated.In addition, it is found that barium chloride has a satisfactory retarding effect on the setting of AACCM in which more than 20% ( by mass ) groud carbonatite was replaced by GGBFS.As a result, a cementitious material, inwhich ground carbona tite rock served as dominative starting material, with 3-day and 28-da y compressive strength greater than 30 MPa and 60 MPa and with continuous strength gain beyond 90 days was obtained.
